Embodiment Construction

[0053] refer to Figure 2-4 , according to one embodiment of the invention, an electromagnetic generator generally designated 100 includes a multilayer structure 101 in which a plurality of layers are sandwiched together. The middle layer 102 is equipped with coils 104, and the two opposite outer layers 106, 108 on each side of the middle layer 102 are respectively provided with respective magnets 110, 112 on their inner working faces. Magnets 110 , 112 may optionally be disposed on respective outer working surfaces of outer layers 106 , 108 . The magnet working faces 114, 116 disposed towards the coil 104 have opposite polarity so that a magnetic flux extends between them. Due to the vibrations applied to the electromagnetic generator 100 , the coil 104 is free to move in the cavity 117 defined between the two opposing outer layers 106 , 108 . The coil 104 moves in the plane of the intermediate layer 102 . Figure 4 Arrows in indicate the direction of movement. The magnet...

Abstract

An electromagnetic generator comprising a multilayer assembly of a first layer carrying at least one magnet, a second layer carrying at least one coil, and a third layer carrying at least one magnet, the at least one magnet of the first and third layers being configured to define therebetween a region of magnetic flux in which the at least one coil is disposed, at least one of the layers being shaped to define a respective displaceable portion thereof which is displaceable by vibration of the electromagnetic generator thereby to cause relative movement between the coil and the magnets and generate an electrical current in the coil.

Description

technical field [0001] The present invention relates to an electromagnetic generator for converting mechanical vibration energy into electrical energy, and a method of manufacturing such an electromagnetic generator. The invention also relates to a magnetic core for an electromagnetic generator for converting mechanical vibration energy into electrical energy, to such an electromagnetic generator comprising such a core, and to a method of producing a magnetic core for an electromagnetic generator. In particular, the invention relates to devices that are micro-generators capable of converting ambient vibrational energy into electrical energy, for example in powering smart sensor systems. Such systems can be used in inaccessible areas where wires cannot actually be connected to provide power or transmit sensor data. Background technique [0002] Currently, there is an increasing level of research and development activity in the area of ​​AC power supplies for microelectromech...
